3.2
Principle of operation
The instrument is suitable for applications in liquids and bulk solids in
vesselsunderdifficultprocessconditions.Thereareapplicationpossibilities in nearly all areas of industry.
The limit level is detected contactlessly through the vessel wall. Neitheraprocessfittingnoravesselopeningisrequired.Theinstrument
isthusidealforretrofitting.
Functional principle
In radiation-based measurement, a Caesium-137 or Cobalt-60 isotope emits focussed gamma rays that are attenuated when penetratingthevesselwallandthemedium.ThePVTdetectorontheopposite
side of the tank receives the radiation. When the intensity of the
radiationdropsbelowadefinedvalue,e.g.duetodamping,thenthe
POINTRAC 31 switches. The measuring principle has proven itself
well under extreme conditions because it measures contactlessly
from outside through the vessel wall. The measuring system ensures
maximum safety, reliability and plant availability independent of the
medium and its properties.
3.3
System limitations
Thereareseveralmeasuringprinciple-specificfactorswhichcaninfluence the measuring result. Keep these factors in mind in order to fully
utilize the capabilities of the instrument with respect to measurement
certainty and reproducibility.

The implemented radioactive isotope and its activity must be selected
according to the properties of the vessel and the medium. The necessary radioactive activity must be calculated on the basis of the plant
data.

Activity of the source
3 Product description
To this end, make use of our planning service for an optimum layout of
the measurement and selection of the isotope. This applies particularly to SIL applications.
Due to the physical properties of the radioactive radiation, the pulse
rateissubjecttoslightfluctuations.Setasuitabledampingleveltoget
a stable measured value.
Non-linearity of the process value
The relation between level and the pulse rate measured by the sensor
is not linear.
External radiation
Externalradiationsourcescaninfluencethemeasuredvalue(e.g.
welding joint tests). In safety-relevant applications, the safety function
must be treated as unreliable as long as the external radiation occurs.
Set up a linearization table to get a linear level signal. For precise
mesurement results, make sure when setting up the linearization
tablethattheactualfillingheightofthemeasuringpointsisenteredas
exactly as possible.
If necessary, you must take measures to maintain the safety function.
Span
Make sure during the planning that for the planned application, a
possiblylargedifferentofthepulseratewithemptyandfullvesselis
reaced. This applies mainly for products with low density or in vessels
with extremely small diameter.

Shielding
Time
Distance
Shielding: Provide good shielding between the radioactive source
and yourself as well as all other persons. Special source containers
(e.g.VEGASOURCE)aswellasallmaterialswithhighdensity(e.g.
lead,iron,concrete,etc.)provideeffectiveshielding.
Time: Stay as short a time as possible in radiation exposed areas.
43388-EN-131119
Distance: Your distance to the source should be as large as possible.
The local dose rate of the radiation decreases in proportion to the
square of the distance to the radiation source.

Mounting instructions
Note:
Along with the planning, our specialists will analyse the conditions of
the measurement loop to dimension the radiation source (isotope)
accordingly.
You get a "Source Sizing" document specifying the required source
activity and containing all relevant mounting information for your
measuring point.
You must follow the instructions of this "Source Sizing" document in
addition to the following mounting instructions.
The following mounting information is applicable as long as there is

For level detection, the sensor is generally mounted horizontally at the
height of the requested limit level. Make sure that there are no struts
or reinforcements at this position in the vessel.
Direct the exit beam of the source container exactly towards the
measuring range of POINTRAC 31.
Fasten the sensor in such a way that it cannot fall out of the holder. If
necessary, provide the sensor with a support from below.
Mount the source container and POINTRAC 31 as close as possible
to the vessel. If there are gaps, secure the area with a safety fence

to get the widest possible radiation angle.
When the sensor is covered by the medium, the radiation damping
is considerably stronger - hence, the switching point is all the more
reliable.
Protection against heat
If the max. ambient temperature is exceeded, you must take suitable
measures to protect the instrument against overheating.
You can protect the instrument by providing a suitable insulation
against the heat or mounting the instrument further away from the
heat source.
Make sure these measures are taken into account already in the planning stage. If you want to carry out such measures later on, contact
our specialists to ensure that the accuracy of the application is not
impaired.
Ifthesemeasuresarenotsufficienttomaintainthemax.ambient
temperature, you could consider using the water cooling system we
offerforPOINTRAC31.

Preparing the connection
Always keep in mind the following safety instructions:
•
•
Connect only in the complete absence of line voltage
If overvoltage surges are expected, overvoltage arresters should
be installed
In this case, the instrument is designed in protection class II. To maintain this protection class, it is absolutely necessary that the ground
conductor be connected to the internal ground terminal. Take note of
the general installation regulations.
Supply voltage and current signal are carried on separate connection
cables if reliable separation is required. The supply voltage range can
differdependingontheinstrumentversion.
Thedataforpowersupplyarespecifiedinchapter"Technical data".
Select connection cable
For power supply, an approved installation cable with PE conductor is
required.
The 8/16 mA current output is connected with standard two-wire cable without screen. If electromagnetic interference is expected which
is above the test values of EN 61326 for industrial areas, screened
cable should be used.
Use cable with a round wire cross section. An outer cable diameter
of6…12mm(0.24…0.47in)ensuresthesealeffectofthecable
entry.Ifcablewithadifferentdiameterorwirecrosssectionisused,
exchange the seal or use an appropriate cable connection. Unused

Cable entry
Generally provide all unused cable entries with suitable blind plugs.
The thin foam rubber washers in the cable glands only serve as a
dust cover during transport.
Cable gland ½ NPT
In the case of instrument housings with self-sealing NPT threads, it
is generally not possible to have the cable glands screwed in at the
factory. The openings for the cable glands are therefore covered with
red protective caps as transport protection.
Before setup you have to replace these protective caps with approved
cable glands or close the openings with suitable blind plugs. Unused
cableglandsdonotprovidesufficientprotectionagainstmoistureand
must be replaced with blind plugs.
The suitable cable glands and blind plugs come with the instrument.

If screened cable is necessary, connect the cable screen on both
ends to ground potential. In the sensor, the screen must be connected
directly to the internal ground terminal. The ground terminal on the
outside of the housing must be connected to the potential equalisation (low impedance).

To avoid this, the cable screen in such applications must be connected only on one end to ground potential in the switching cabinet.
The cable screen must not be connected to the inner ground terminal
in the sensor and the outer ground terminal on the housing must not
be connected to potential equalization!
Information:
The metal parts of the instrument are conductively connected with
the inner and outer ground terminal on the housing. This connection
is either a direct metallic connection or, in case of instruments with
external electronics, a connection via the screen of the special connection cable.
Youcanfindspecificationsonthepotentialconnectionsinsidethe
instrument in chapter "Technical data".
Connection technology
The voltage supply and signal output are connected via the springloaded terminals in the housing.
The connection to the display and adjustment module or to the interface adapter is carried out via contact pins in the housing.
Connection procedure
Proceed as follows:
The procedure applies to instruments without explosion protection.
1. Unscrew the big housing cover
2. Loosen compression nut of the cable entry
3. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.

Functional safety (SIL)
6.1
Objective
In case of dangerous outages, processing facilities and machines can
cause risks for persons, environment and property. The risk of such
outages must be judged by the plant operator. Dependent thereon are
measures for risk reduction through error prevention, error detection
and fault control.
The part of plant security depending on the correct functioning of
safety-related components for risk reduction is called functional
safety. Components used in such safety-instrumented systems (SIS)
must therefore execute their intended function (safety function) with a
definedhighprobability.
The safety requirements for such components are described in
the international standard IEC 61508, which sets the measure for
unique and comparable judgement of instrument safety and hence
contributes to worldwide legal certainty. Depending on the degree
of required risk reduction, we distinguish between four safety levels,
from SIL1 for low risk to SIL4 for very high risk (SIL = Safety Integrity
Level).
6.2 SILqualification
Additional characteristics When developing instruments which can be used in safety-instruand requirements
mented systems, the focus is on avoiding systematical as well as
determining and controlling random errors.
Here the most important characteristics and requirements from the
perspective of functional safety according to IEC 61508:
•
•
•
•
•
•
Internal monitoring of safety-relevant circuit parts
Extended standardization of the software development
In case of failure, switching of the safety-relevant outputs to a
definedsafestatus
Determinationofthefailureprobabilityofthedefinedsafetyfunction

Safety concept of the parameterization
The following tools are permitted for parameterization of the safety
function:
•
•
The integrated display and adjustment unit for on-site adjustment
The DTM suitable for the signal conditioning instrument in conjunction with an adjustment software according to the FDT/DTM
standard, e. g. PACTware
Note:
For operation of the POINTRAC 31 the DTM Collection version 1.67.2
orhigherisrequired.Themodificationofsafety-relevantparametersis
only possible with active connection to the instrument (online mode).
Reliable parameterization To avoid possible errors during parameterization in a non-safe user
environment,averificationprocedureisusedthatmakesitpossible
to detect parameterization errors reliably. For this, safety-relevant
parametersmustbeverifiedbeforetheyarestoredinthedevice.In
normal operating condition, the instrument is also locked against
parameter changes through unauthorized access. This concept applies to the adjustment on the instrument but also to adjustment with
PACTware with DTM.
Safety-relevant parameters
For protection against unwanted or unauthorzed adjustment, the set
parameters must be barred from unauthorized access. For this reason, the instrument is shipped in locked condition. The PIN in delivery
status is "0000".
Whenshippedwithaspecificparameteradjustment,theinstruments
are accompanied by a list with the values deviating from the basic setting. By entering the serial number, the list is available as a download
under "www.vega.com/VEGA-Tools".
Afterachange,allsafety-relevantparametersmustbeverifiedand
confirmedviaacharacterstringcomparison.
The parameter settings of the measurement loop must be documented. For this purpose, the document "SIL device settings" is attached to each instrument listing all safety-relevant parameters in the
shipping status as well as containing free space for own notes. This
document is also available on our homepage. In addition, a list of the
safety-relevant parameters can be stored and printed via PACTware/
DTM.
For each parameter change, the instrument must be unlocked via a
PIN (see chapter "Setup steps - Lock adjustment"). The device status
is indicated by the symbol of an unlocked or locked padlock.
Unsafe device
status
Warning:
If adjustment is enabled, the safety function must be considered
as unreliable. This applies until the parameterization is terminated
correctly. If necessary, other measures must be taken to maintain the
safety function.

Procedure
Check if the correct language is already set for the display. If not, you
can change the language in the menu item "Display/Language".
Start with the setup of POINTRAC 31.
In the main menu point "Setup", the individual submenu points
should be selected one after the other and provided with the correct
parameters to ensure optimum adjustment of the measurement. The
procedure is described in the following.
Stick with the normal sequence of the menu items as closely as possible.
Setup
Setup - Measurement
loop name
In this menu item you can assign an unambiguous name to the sensor or the measurement loop.
Setup/Isotope
In this menu item you can adjust the POINTRAC 31 to the integrated
isotope in the source container.
This parameter is described in the operating instructions manual
"Display and adjustment module".
For this purpose, check which isotope is integrated in the source
container.Youcanfindthisinformationonthetypelabelofthesource
container.
43388-EN-131119
Through this selection, the sensitivity of the sensor is adapted
perfectly to the isotope. The normal reduction of the emitter activity is
hence considered through the radioactive decay.
The POINTRAC 31 requires this information of the automatic decay
compensation. This ensures an interference-free measurement over
the complete life time of the gamma emitter - an annual recalibration
is not necessary.
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.

This menu item enables adaptation of the sensor to the requested
application. Only the application "Point level" can be selected with
your instrument.
With this menu item the natural background radiation can be faded
out.
For this purpose, the POINTRAC 31 measures the natural background radiation and sets the pulse rate to zero.
In the future, the pulse rate from this background radiation will be
automatically deducted from the total pulse rate. This means: only
the component of the pulse rate originating from the source will be
displayed.
The source container must be closed for this setting.
Setup/Unit
In this menu item you can select the temperature unit.
Setup - Adjustment mode in this menu item you can select if you want to carry out a single or
double point adjustment on the sensor.
With the double point adjustment, the Delta I value is selected automatically.
We recommend selecting the double point adjustment. To use this,
you must be able to change the level of the vessel so as to carry out
the adjustment of the sensor with full status (covered) and with empty
status (uncovered).
Hence, you will get a very reliable switching point.

uncovered (single point
adjustment)
This menu item appears only if you have selected "Single point
adjustment" as adjustment mode (Setup/Adjustment mode).
In this menu item you determine the point at which the POINTRAC 31
should switch in uncovered status.
Empty the vessel until the sensor is uncovered.
For this enter the requested pulse rate manually or let the rate be
determined by POINTRAC 31. Automatic determination of the pulse
rate should be given preference.
The pulse rate is entered in ct/s. This is the number of counts per
second, i.e. the measured gamma radiation reaching the sensor.
Prerequisites:
•
•
Radiation is switched on - Source container is set to "ON"
There is no medium between source container and sensor
You can enter the value for "Adjustment uncovered" (ct/s) manually.
You can have the value for "Adjustment uncovered" determined by
POINTRAC 31.
Setup/Delta I (single
point adjustment)
This menu item appears only if you have selected "Single point
adjustment" as adjustment mode (Setup/Adjustment mode).
In this menu item you can adjust at which percentage value of the
max. pulse rate the sensor should switch over.
43388-EN-131119
Since in most cases the radiation is almost completely absorbed
when the sensor is covered, the pulse rate when the sensor is covered is very low.
Thechangebetweenthetwostatusesissufficientlyclear.
Hence a percentage value of 90 % for the Delta I value is recommended.
You select lower values for sensitive detection of material cones or
buildup which cause only partial absorption of the radiation.

This menu item appears only if you have selected under adjustment
mode (setup/adjustment mode) the "Two-point adjustment".
In this menu item you can set the min. pulse rate (ct/s) at which the
sensor should switch over.
Fill the vessel until the POINTRAC 31 is covered.
You thus get the min. pulse rate (ct/s) for the "covered" adjustment.
Enter the requested pulse rate manually or let the rate be determined
by POINTRAC 31. Automatic determination of the pulse rate should
be given preference.
You can enter the adjustment point (ct/s) manually.
You can let the adjustment point be determined by POINTRAC 31.

Saving the parameter adjustment data
We recommended noting the adjusted data, e.g. in this operating
instructions manual, and archiving them afterwards. They are thus
available for multiple use or service purposes.
If the instrument is equipped with a display and adjustment module,
the data in the sensor can be saved in the display and adjustment
module. The procedure is described in the operating instructions
manual "Display and adjustment module" in the menu item "Copy
sensor data". The data remain there permanently even if the sensor
power supply fails.
The following data or settings for adjustment of the display and adjustment module are saved:
•
•
•
All data of the menu "Setup" and "Display"
In the menu "Additional adjustments" the items "Sensor-specific
units, temperature unit and linearization"

For parameter adjustment of the sensor via a Windows PC, the configurationsoftwarePACTwareandasuitableinstrumentdriver(DTM)
according to FDT standard are required. The up-to-date PACTware
version as well as all available DTMs are compiled in a DTM Collection. The DTMs can also be integrated into other frame applications
according to FDT standard.
Note:
To ensure that all instrument functions are supported, you should
always use the latest DTM Collection. Furthermore, not all described
functionsareincludedinolderfirmwareversions.Youcandownload
the latest instrument software from our homepage. A description of
the update procedure is also available in the Internet.
Further setup steps are described in the operating instructions manual "DTM Collection/PACTware" attached to each DTM Collection and
which can also be downloaded from the Internet. Detailed descriptions are available in the online help of PACTware and the DTMs.
